Abstract
Abstract The paper introduces a computer-based methodology, the aim of which is to determine a watering-place radius for flocks of sheep grazing in distant pasture lands within the arid ecosystem. All calculations leading to the quantitative values are performed through mathematical modeling which is the base of the methodology we propose. The mathematical modeling is performed through some analytical method including the sequential parameters calculation with mathematical formulas. The object was theoretically described, an algorithm was compiled in the form of a block diagram, and a computer program SUARU in the QBASIC language was developed. A series of computational experiments was carried out, aimed at analyzing, interpreting and comparing the analytical modeling outcomes. At the same time, graphical dependencies are presented to show clearly the dependence between the calculation results and the source data. The calculation methodology allows modeling the object of study depending on various values of significant parameters and applying it in practice by drawing up appropriate recommendations for farms which deal with sheep breeding when grazing lands of the arid ecosystems are used.
